High Voltage Power Distribution Units (HV PDUs) are critical components in modern electric and hybrid platforms. What is a high voltage box? The High Voltage Power Box combines the functionality of an Onboard Charger (OBC), a DC/DC converter and a PDU (Power Distribution Unit). It is enclosed in a corrosion-resistant metal box with transformers and low-voltage units, and supports two wiring modes on the high-voltage.

These faults can be caused by natural factors like lightning, tree branches, or animals, as well as technical issues like equipment failure or overload. European-style box-type substations are widely used in urban power distribution systems, industrial parks, photovoltaic power plants, and transportation hubs due to their compact size, complete functionality, convenient installation, and safe operation. However, in actual applications, distribution boxes often encounter a series of problems, which not.
